Tandem: Practice Languages

Tandem connects language learners directly with native speakers across 300-plus languages, including 12 sign languages, through one-on-one text and audio chat as well as group audio rooms called Parties. Released back in 2015 and still actively updated, the app has built a community large enough to generate 37,000 store ratings averaging 4.6. It is not a structured course platform. The value here is raw conversation practice with real people, which makes it genuinely different from gamified vocabulary apps.

Where It Delivers

The breadth of language coverage is hard to argue with. Finding a partner for Spanish or Korean is fast, but the inclusion of sign languages and smaller regional languages sets Tandem apart from most competitors. The Parties feature adds a low-stakes group audio environment that suits learners who are not yet ready for a fully committed one-on-one session. For conversational fluency specifically, practicing with a motivated native speaker beats most app-based drills.

The Friction Points

At 334 MB the install is substantial for a chat-focused app, and the free tier appears to gate certain features behind in-app purchases, which is not spelled out clearly upfront. Because the experience depends entirely on partner availability and willingness, quality is inconsistent. A learner targeting a less-common language may wait longer for a good match, and there is no curriculum to fall back on when the conversation side runs dry.

Who Should Download It

Tandem suits intermediate learners who already have basic grammar in place and want to convert that knowledge into real spoken or written fluency. Absolute beginners may find the unstructured format frustrating without supplementary study. It also works well for people preparing for travel or relocation who need practical, culturally grounded conversation rather than textbook sentences. The sign language coverage makes it a notably inclusive option compared to most language apps.
